Some things I’ve learned about Washington Boulevard from Wikipedia: Washington Boulevard was constructed in the early 20th Century to facilitate vehicular access to the Hotel La Pintoresca at Fair Oaks & Washington, and to service riders on the East Washington Streetcar line. The line ran for 2.5 miles between Los Robles Avenue and Santa Anita Avenue. Washington Boulevard originally terminated at Arroyo Boulevard and Altadena Drive. An extension west to Linda Vista was built in the 1940s and another southeast to Pasadena High School in the 1960s.

Trivia: In Pasadena, five streets are named after U.S. Presidents and eight are named after states. Washington Boulevard is named after the state because of its east-west orientation (all streets named for presidents are north-south). Now you know! 🙂
